ATTACHMENT FOR OPEN FIRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 410,169, dated. September 3, 1889,

Application filed August-24, 1888: Serialll'o. 283,613- (No modeld To all whom itmay concern;

Be it known that I, DOUGLAS P. LEWIS, a citizen of the United Seates, residing in Oincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Attachments for Open Fire- Places, of which the following is a specification.

This invention relates to the improvement of an attachment to open fire-places which was patented in the United States of America by Douglas P. Lewis, Andrew M. Johnson, and John W. J ohn,dated March 22, 1887, and numbered 359,868; and the principal object of the new improvement is to construct the parts in such a manner as to still give a high degree of economy in the saving of fuel, and

at the same time to better adapt the attach-' ment to every variety of fire-places without the outlay of so much extra timeand money as has hitherto beennecessary in many cases.

Referring to the drawings, Figure 1 is a view of the improved attachment as it appears when separated from the fire-place, with parts broken away to show circulation of the heat-ed gases. Fig. 2 is a back view of the attachment, showing the relative position of the parts. Fig. 3 is a sectional view near one side on the dotted line 3, Fig. 2, showing also a section of the brick-work of the chimney and the position in the fire-place the attachment occupies when ready for use. In Fig. 3 is also shown part of the the top of a mantel.

The general construction is the same as the attachment shown in Patent No. 359,868, before referred to, in which the parts A, B, and B are hollow castings. The part A forms a hollow lintel, which at each end is in communication with the top end of the hollow jambs B and B, and this hollow lintel has an opening at the under side, which extends its whole length from the inside of 1101- low jamb B to the inside of hollow jamlo B. The jambs B and B stand upon the hearth, and at the back part of each, close to the hearth, is an openingD and D. At this point is the principal improvement upon Patent No. 359,868 hereinbefore referred to.

In my improved attachment herein de described the hollow base shown in Patent No. 359,868, hereinbefore referred to, is entirely dispensed with, and in the place of this of cast-iron of about eight inches in width.

The back plate has a door I, which can be opened for the purpose of cleaning out the soot which may deposit at the rear of the attachment. The side and back plates, which form the ash-pit, are flanged laterally at the top edge to increase their thickness, and thus form the foundation for the firebrick lining of the attachment.

It must be understood that in the application of this attachment the width between the jambs and the height between the arch and hearth of a fire-place form an opening which is smaller than the greatest height and width of the attachment, so that when the attachment is applied to a fire-place the hollow jambs B and 13, together with the hollow lintel A, have a position in front and entirely outside of the brick-work of the chimney, as shown in Fig. 3, and only the rear projecting parts have a position inside thej ambs and arch of the fire-place, as shown in Figs. 2 and 3. The

entire opening of the fire-placedown to the,

hearth is thus covered by the. attachment. The outside width of the box which forms the ash-pit is always less than the width between the jambs of the fire-place, so that when the attachment is in proper position a space is left at each side of the ash-pit box to form passages which extend directly to the rear and connect the flue at the back of the attachment with the openings D and D at the lower end of the hollow parts B and B. The bottom of these side passages is the hearth, and the top is formed by horizontally-projecting plates N and N, one of these plates being plainly shown just above opening D in Fig. 2.

N o grate is shown in the attachment; but if one is placed in the usual position above the ash-pit and a fire built the heated air, together with the products of combustion, will rise and be carried by the inward draft at the long opening at the under side of the hollow lintel A to the right and left, thence downward through the hollow jambs B and B to the openings D and D, thence directly rearward through the passages at each side of the ash-pit R; and thence into and upward in the flue L. There is a damper placed in the throat of the hollow lintel A, which can be either wholly or partially closed to stop the draft where it is necessary to bank the fire in the grate, or for any other purpose that may arise in practice.
